Abstract

Scientific visualization is the process whereby numerical data is transformed into a visual form to augment the process of discovery and understanding. Visualizing the data generated by large-scale, transient, three-dimensional finite element simulations poses many challenges due to geometric complexity, the presence of multiple materials and multiple element types, and the inherent unstructured nature of the meshes. In this paper, the direct use of finite element data structures, nodal assembly procedures, and element interpolants for volumetric adaptive surface extraction, surface rendering, vector grids and particle tracing is discussed. A brief description of a {open_quotes}direct-to-disk{close_quotes} animation system is presented, and case studies which demonstrate the use of isosurfaces, vector plots, cutting planes, reference surfaces and particle tracing are then discussed in the context of several case studies for transient incompressible viscous flow, and acoustic fluid-structure interaction simulations. An overview of the implications of massively parallel computers on visualization is presented to highlight the issues in parallel visualization methodology, algorithms. data locality and the ultimate requirements for temporary and archival data storage and network bandwidth.

GRIZ. Finite Element Results Visualization for Unstructured Grids

Technical Report Dovey, D; Spelce, T; Christon, M

GRIZ is a general-purpose post-processing application supporting interactive visualization of finite element analysis results on unstructured grids. In addition to basic pseudocolor renderings of state variables over the mesh surface, GRIZ provides modern visualization techniques such as isocontours and isosurfaces, cutting planes, vector field display, and particle traces. GRIZ accepts both command-line and mouse-driven input, and is portable to virtually any UNIX platform which provides Motif and OpenGl libraries.

GRIZ: Finite element analysis results visualization for unstructured grids. User manual

Technical Report Dovey, D; Spelce, T

GRIZ supports interactive visualization of finite element analysis results on unstructured grids. GRIZ is a general-purpose post-processing application which is designed to work with a variety of an analysis codes. Currently, GRIZ is capable of calculating and displaying derived variables for the DYNA3D, NIKE3D and TOPAZ3D analysis codes. GRIZ reads in data files in the ``MDG plotfile`` format. GRIZ provides support for modern 3D visualization techniques such as isosurface display, cutting planes and display of vector data. GRIZ also incorporates the ability to animate data over time and to store animation frames to a video disk. GRIZ is designed tomore »« less

Visualization of transient finite element analyses on large unstructured grids

Conference Dovey, D

Three-dimensional transient finite element analysis is performed on unstructured grids. A trend toward running larger analysis problems, combined with a desire for interactive animation of analysis results, demands efficient visualization techniques. This paper discusses a set of data structures and algorithms for visualizing transient analysis results on unstructured grids and introduces some modifications in order to better support large grids. In particular, an element grouping approach is used to reduce the amount of memory needed for external surface determination and to speed up ``point in element`` tests. The techniques described lend themselves to visualization of analyses carried out in parallelmore »« less

Parallel Simulation of Three-Dimensional Free Surface Fluid Flow Problems

Conference BAER, THOMAS; SACKINGER, PHILIP; SUBIA, SAMUEL

Simulation of viscous three-dimensional fluid flow typically involves a large number of unknowns. When free surfaces are included, the number of unknowns increases dramatically. Consequently, this class of problem is an obvious application of parallel high performance computing. We describe parallel computation of viscous, incompressible, free surface, Newtonian fluid flow problems that include dynamic contact fines. The Galerkin finite element method was used to discretize the fully-coupled governing conservation equations and a ''pseudo-solid'' mesh mapping approach was used to determine the shape of the free surface. In this approach, the finite element mesh is allowed to deform to satisfy quasi-staticmore »« less
